TRANSMISSION Specification of Letters Patent.

Patented Nov. 18, 1919.

Application Med It! 88, 1919. Serial No. 299,146.

To all whom it may concern:

Be it known.that- I,"Hi;mnri Faun Hons, Jr., a citizen or the'UnitedStates, and a resident of San Francisco, in the county 5 of SanFrancisco and State of California, have invented certain new and usefulIm rovements in Transmission-Bands, of

which the following is a specification.

This invention isan improqement in brake bands and hasreference moreparticularly to braking means used in connection with automobiletransmissions.

An object of this invention is to provide a brake band that can beeasily put in a car and which may be shiftedup and down allowing theband to slip around within the transmission case with ease Anotherobject is to provide a band for transmissions which will retain itsoriginal and normal shape and size.

Another ob'ect is to provide a band made up of remova 1e parts.

WVith these and other objects which will become apparent as thedisclosure proceeds, the invention consists in certain novel featuresof'construction, arran ement and combination of parts, as will bedescribed and pointed out'in the claims reicrence being had to theaccompanying cirawin in which igure 1 is an elevation, artly in sectionof my improved brake band .Fig. 2 is a top plan view of the same; andFig. 3,is an enlarged .detail perspective 85 view of one of thestraining ears.

In devices of the character upon which the present invention is desi edto improve it is usualto make the band which are put around the drums ofthe transmission, as a single mem r or a one-piece band, and to applythese and remove them they must be bent out of shape, causinggreattrouble and loss of time in installing, largely due to the fact that thebands are-almost a complete circle. I

' To overcome these objections and defects, construct my band oftwosubstantially semi-circular sections or members 5, of steel having moreor less resiliency, the sections having a bin (1 connection 6 at theirlower ends. The riction lining 7 is of a sin le length, and is securedin is proper relation to the inner, face of the wo-part band by 56-:"At'the ree ends of the respective mem-,

ereinafter fully.

of cold rolled steel, and a1 essary as in single Furth bers of the band,I provide a head or guide pin 9 ri idly connected to the member orintegral t erewith, said pin being positioned at the lateral center ofth band member and sli htly back from the free end of same. 60

he straining pins 10 are desi' ed to hold the straining ears in place analso from pulliniforward or moving backward. These ears w ich areremovable from the band include a base portion 11, the lower face ofwhich is made on approximately the same are as the band section to whichit is applied and is provided with a perforation in which the pin 10fits.

Spaced apart outstanding lugs 13 are provided at its forward end, andsidewalls or flanges 14 which merge into the back walls of the saidlugs; the front end of the ears prO ecting slightly beyond thetransverse! plane of the lugs,-and the base is provided 76 with a notchor cutout 15,, within which the head or guide pin 9 fits.

The straining pins are provided with pussages just above the uppersurface of the base and into these passa are forced the cotter pins 16which hol the ears removably against the ends of the band sections;these cotter pins, in addition to erforming the, function just stated,are a'so used. to

prevent the ears from moving upwardly .away from the band sections.

The lining 7 is of the character used with the ordinary transmissionsandcan be read ily removed as it is held to the inner face of the band bsplit rivets 8.

As the hand sections are referably made other parts including the earsbein made of steel, the band as aunit will withstand hard usage.

The band bein made in two sections hlngedly connected renders-it easy toput in the car transmission case, as it can be shifted up and down,allowing the band to slip around, inside the transmission base withcase. No bending of the band is nec member bands such as are in commonuse. 7

ermore .the cars can be removed with ease as there IS nothing to becomewed a V 108' Again, the band being in two sections, al-

, .lows one section to be lifted away from the crank case and the othersection easily started around the drum of the transmission,

whereas in the single section type hand one 110 end of the band hits theside of the-crank case and only by bending the band away from the casecan it be started in the case.

By providing the side flanges or walls 1.4 which extend outwardly beyondpins 10 and the cotter pins 16, they are protected against being brokenby accident and from proper cooperating relation with each other.

I claim:

1. A device as herein characterized and consisting of a pair of steelband sections hin dly connected at one end, detachable straining ears atthe free ends of said sections, said ears including a base plate havinga notched front on and spaced apart lugs or posts adjacent the frontend, straining and holding means engaging the rear portion of said baseplate, and guide pins projecting from the outer face of said sections attheir free ends, and fitting within the aforesaid notches.

2. A brake band for transmissions consisting of a pair of semi-circularsteel band sections hingedly connected at one end, a straining earmounted on each section at its free end, said ears including a baseplate fittin on said sections, spaced apart outstan mg In S 'or postsadjacent the front end of said ase plate, said plate notched or out outbetween said lu s, a guide in carried by the sections an fitting withinsaid notch, a straining pin carried by said sections and extending throuh the base plate intermediate its front and rear ends, and meansengaging said straining pin for holding the base plates to the bandsections, and against vertical movement.
